This invention relates to injector needles, and aims to provlde a needle adapted to co ntrol the amount of liquid injected through 1t.

. Injector needles embodying the present 5' invention are especially adapted for use w th the dyeing machine shown in my co-pendmg applichtion, Serial No. 100,486, filed Aprll 8,

1926, of which this application is a division.

They may also be used in the dyeing machines shown in U. S. Patents Nos. 1,577 ,884 and 1,606,196, issued to Henry E. Van Ness on March 23, 1926, and November 9, 1926,

respectivel and for other purposes.

The needles used in the Van Ness dyeing l6 machines shown in the patents referred to were provided with longitudinal grooves extending their entire length. When inserted in a chuck in a nozzle, such a needle provides for free passage for liquid which may enter through the rear end of its longtudlnal Y groove. Such needles, therefore, do not materially retard the flow of liquid through them.

In accordance w th'the present invention,

injector needles are provided with a longitudinalgroove terminating at a point spaced from their rear ends. When such a needle 6 is placed in a chuck in a pro ector nozzle, such, for example, as that shown 1n Van lfIess Patent No. 1,577,884, the llqllld forced into the rear end of the nozzle cannot enter directly into the groove of the needle. The liquid is, therefore, retardedsotl at, under given conditions of pressure and t me nterval, a smaller quantity of llquld 1s lnjected than would be injected with a Nes A further feature of the lnventlon consists in providing the portion of the needle.

needle behind the rear end of the groove 40 with a bore extending from the rear end of the needle into the rear end-of the. groove.

By making this bore of any desired size, any
